3087無縫鋼管現貨結實耐用 可送貨，GB3087無縫鋼管是(shi)用(yong)鋼錠或實心管坯(pi)經(jing)(jing)穿孔制成毛管，然后經(jing)(jing)熱(re)軋(ya)(ya)、冷軋(ya)(ya)或冷撥制成。3087主要(yao)是(shi)用(yong)于(yu)承壓(ya)，8163一般應用(yong)于(yu)流體(ti)輸送(song)，但行業有交(jiao)叉，也有拿3087替代8163要(yao)求(qiu)高的。

　　1、GB3087無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)是用鋼(gang)錠或實心管(guan)(guan)(guan)(guan)坯經(jing)穿孔制(zhi)成(cheng)毛管(guan)(guan)(guan)(guan)，然后(hou)經(jing)熱軋(ya)、冷軋(ya)或冷撥(bo)制(zhi)成(cheng)。GB3087無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)在我國鋼(gang)管(guan)(guan)(guan)(guan)業中(zhong)具有(you)重(zhong)要的(de)地位，它是管(guan)(guan)(guan)(guan)狀(zhuang)的(de)鋼(gang)材。2、它有(you)無(wu)縫(feng)鋼(gang)管(guan)(guan)(guan)(guan)、熔接(jie)(jie)鋼(gang)管(guan)(guan)(guan)(guan)、鍛(duan)接(jie)(jie)鋼(gang)管(guan)(guan)(guan)(guan)、熱壓出鋼(gang)管(guan)(guan)(guan)(guan)等，可作(zuo)瓦斯管(guan)(guan)(guan)(guan)、自來水管(guan)(guan)(guan)(guan)、化學工廠的(de)配管(guan)(guan)(guan)(guan)等，用處(chu)極廣。

　　3、GB3087又叫低中(zhong)壓(ya)鍋(guo)爐(lu)(lu)用無(wu)縫(feng)(feng)管(guan)(guan)(guan)(guan)(guan)(GB3087-2008)是(shi)用于制造(zao)各種結構低中(zhong)壓(ya)鍋(guo)爐(lu)(lu)過熱蒸汽管(guan)(guan)(guan)(guan)(guan)、沸水管(guan)(guan)(guan)(guan)(guan)及機車鍋(guo)爐(lu)(lu)用過熱蒸汽管(guan)(guan)(guan)(guan)(guan)、大煙管(guan)(guan)(guan)(guan)(guan)、小煙管(guan)(guan)(guan)(guan)(guan)和拱磚管(guan)(guan)(guan)(guan)(guan)用的優質碳素(su)結構鋼(gang)熱軋和冷拔(軋)無(wu)縫(feng)(feng)管(guan)(guan)(guan)(guan)(guan)。GB3087-2008《低中(zhong)壓(ya)鍋(guo)爐(lu)(lu)用無(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)(guan)(guan)(guan)》規定。

　　4、各(ge)種結(jie)構鍋爐用(yong)鋼管(guan)規(gui)格，外(wai)(wai)徑(jing)10~426mm，共計(ji)43種。壁(bi)厚1.5 ~26mm共計(ji)29種。GB3087-2008《低(di)中壓鍋爐用(yong)無(wu)縫鋼管(guan)》和(he)GB5310-2008《高壓鍋爐用(yong)無(wu)縫鋼管(guan)》的(de)規(gui)定(ding)。外(wai)(wai)觀質量:鋼管(guan)內外(wai)(wai)表(biao)面不允許有裂縫、折疊、軋折、結(jie)疤、離層和(he)發紋。這些缺陷應完全清(qing)(qing)除掉。清(qing)(qing)除深度(du)不得超過公稱(cheng)壁(bi)厚的(de)負偏差，其清(qing)(qing)理處(chu)實際壁(bi)厚不得小(xiao)于壁(bi)厚所允許的(de)*小(xiao)值。

　　GB3087執行(xing)新標準

　　GB8163-2008輸(shu)送流(liu)體(ti)用(yong)無縫鋼(gang)(gang)管(guan)標準，適(shi)用(yong)于(yu)輸(shu)送流(liu)體(ti)用(yong)一般無縫鋼(gang)(gang)管(guan)。GB8163中10、20#鋼(gang)(gang)限于(yu)額定出(chu)口熱(re)水溫度(du)(du)(du)(du)(du)低于(yu)120度(du)(du)(du)(du)(du)的(de)(de)鍋爐(lu)(lu)。導熱(re)油(you)使用(yong)溫度(du)(du)(du)(du)(du)范圍一般在200-450度(du)(du)(du)(du)(du)。長期在高溫的(de)(de)環(huan)境下流(liu)通，應采用(yong)GB3087-82標準。而有機熱(re)載(zai)體(ti)鍋爐(lu)(lu)中導熱(re)油(you)的(de)(de)溫度(du)(du)(du)(du)(du)一般在300-400度(du)(du)(du)(du)(du)，所以必須用(yong)3087的(de)(de)管(guan)子。
